I did NOT mean serial TTY. I meant the serial bitstream
between the controller
and the drive's read/write part! The discussion went into another direction.

For RK05 it IS trivial. I read the manual in the meantime :-)
Yebbut...having a grand old system like a PDP-11 on
"life support" by
connecting it to a PC is something that I (and others) find extremely
distasteful. A standalone device would definitely have a market.
No, my solution
would be a card with a mass storage interface that can be
plugged into the bus. It would then play controller+drive(s)+media.
Who would be willing to pay $300+ for an RK05 or RL01/02 emulator which can be
plugged in instead of a real drive?
Another aspect of drive level emulation is that you would have to store raw
sector data which could not be used on a PC without a tool playing the specific
controller in software...
